本発明は、非限定的な例として示され且つ添付の概略図面を参照して説明される好ましい実施形態に言及する以下の記載により理解されるであろう。
本発明による導光被覆要素の第２部分の概略斜視図と概略断面図である。 計器パネルの一部の概略斜視断面図と、本発明による導光被覆要素の概略図である。 The invention will be understood by the following description which refers to preferred embodiments which are given as non-limiting examples and which are described with reference to the accompanying schematic drawings.
FIG. 2 is a schematic perspective view and a schematic cross-sectional view of a second portion of a light guide covering element according to the present invention. 1 is a schematic perspective sectional view of a part of an instrument panel and a schematic view of a light guide coating element according to the present invention.

本発明による計器パネルの表示装置は、通常、特に少なくとも１つの目盛盤を含む表示面又は表示領域３０を備える。   The display device for an instrument panel according to the invention usually comprises a display surface or display area 30, in particular comprising at least one dial.

指針を備えた第１指示計器２１が表示領域３０と関連付けられ、指針を備えた第１指示計器２１は回転軸を中心に回転駆動することができる。   A first indicating instrument 21 having a pointer is associated with the display region 30, and the first indicating instrument 21 having a pointer can be driven to rotate about a rotation axis.

表示領域は、回転軸に関して中央の第１部分３１と周辺の第２部分３２とを有し、指針を備えた第２指示計器２２が、表示領域３０の周辺第２部分３２を少なくとも部分的に照明するために設けられる。このために、指針を備えた第２指示計器２２は、好ましくは、（ユーザの通常の視点から見て）表示領域３０の面の後ろにあり（隠れ）且つ回転軸、好ましくは指針を備えた指示計器２１を有する第１指示計器と同じ回転軸を中心に回転駆動することができる指針を有する指示計器である。   The display area has a central first portion 31 and a peripheral second portion 32 with respect to the rotation axis, and the second indicator 22 having a pointer at least partially surrounds the peripheral second portion 32 of the display area 30.
